Not until + Inversion. Here inversion "did + Subject + V(infinitive). Therefore, begun -> begin

"Began" should be "begin" because after a sentence initial negative word (Not), there is inversion of subject-verb, so the normal word order "the birthrate began" turns into "did the birthrate begin." The auxiliary verb "do" takes the past form "did," and the main verb takes the infinitive form "begin," the same word order as a question.
